Savela was flown by helicopter to Delray Medical Center, where he is listed in critical condition.

Investigators say Ikuro Ohigashi, 65, was impaired, telling them she took two Xanax and a Vicodin before leaving her Palm Beach home.

Ohigashi was arrested on DUI charges.

Further investigation led deputies to believe that she may have been involved in an earlier hit-and-run crash on Palm Beach.

According to the police report, a witness saw a woman driving a Mitsubishi SUV crash into a Dumpster and then a parked car. The witness said the driver got out, looked around, then got back in her SUV and drove off.

Because she told deputies she was planning to leave for Japan this week, prosecutors requested no bond. Ohigashi's attorney objected.

"She's 65 years old," Ohigashi's attorney told the judge. "She's owned her home in Palm Beach since 1984. She's been a Palm Beach County resident since 1982. She's linked to a sizable business that total employs about 200 people."

Ohigashi was granted a $100,000 bond, but she was ordered to surrender her passport.
